dselect update warns gpg sig of Release file bad

[Travis Crump <pretzalz@techhouse.org>]

When I try to do dselect update[I've tried several times throughout the 
day], I get an error that the Release file signature is bad:

W: GPG error: http://http.us.debian.org testing Release: The following 
signatures were invalid: BADSIG F1D53D8C4F368D5D Debian Archive 
Automatic Signing Key (2005) <ftpmaster@debian.org>
W: GPG error: http://http.us.debian.org unstable Release: The following 
signatures were invalid: BADSIG F1D53D8C4F368D5D Debian Archive 
Automatic Signing Key (2005) <ftpmaster@debian.org>
W: You may want to run apt-get update to correct these problems
Merging Available information
Replacing available packages info, using /var/cache/apt/available.
Information about 17117 package(s) was updated.

Anyone know what the problem is/has anyone else experienced this?
